I'm not sure about this change. In the other benchmarks, len is a message length in bytes I think. Here, it is a number of iterations, so len is kind of misleading because it's not a length. We tend to use n for this sort of thing instead.

I'm not opposed to this, but would be curious what others thought. @nodejs/benchmarking @mscdex

Actually, I see that you already set n to 1 when you launch the benchmarks, so maybe this should just be n and that's that?

Yes, we should be more consistent and use n where possible. There are some benchmarks like this and others that use thousands or millions though. I prefer to just use n, even if the values are large, for consistency.

Yeah I think I renamed this to len because I mistook this one for another benchmark when editing :S..this should've been n, good catch!

Updated to use n in spawn-echo.js.

FWIW, sequential/test-benchmark-child-process hangs on some Windows CI.

Oh good, it's not just me. test-benchmark-child-process definitely appears to be somewhat flaky on Windows CI.

This landed despite the added test failing on the Windows CI run for this PR. :-(

Seems to run OK on all the CI Windows types except Windows 2016. Maybe yes.exe isn't installed there? @nodejs/build

Although I don't think it would hang if that's the case...it would exit with ENOENT, I think.

Oh no, sorry for the trouble, should've checked the new CI :(

Opting to let this bake a while longer. This should land with #12518 (and possibly #12561)
